Fascinating. I'm glued to this thread.
How quickly can you decelerate from 160 and how much reaction time do you get in that situation? Is there a muscle memory mechanism in place for the increased steering resistance from slowing down?
"My point was to explain to a car driver what a motorcyclist has to do / what he is likely capable of doing at 150+ mph."
I think the point you're trying to make is this, and please correct me if I'm wrong.
Car drivers have nothing with which to compare the acceleration rate of a large cc sport bike. Therefore, it's the ability to plan moves ahead of time, and not have the elements of the equation change afterwards. If it does, you are extremely limited in options, and most likely doomed.
For instance, if someone unfamiliar with the acceleration rate of a sport bike, is asked to take one and accelerate as fast as possible towards a visible point, and let off at the right time to stop, most would pick a point much too late to do so.
I also tell motorcycle riders to ride with the thought that everything and everyone on the road is out to get you.
I never make anyone nervous, which closing and passing at that speed differential would cause. However if it was on a closed course and the cage didn't use signals and purposely attempted to move and hit me during the pass, or attempted to cause a rear end at that differential, they wouldn't be able to do it.
I agree that it's best for a cage seeing that kind of dangerous action should stay put, because someone doing that most likely can't ride anyway.
"...you'll have already traveled an additional 200 or so feet closer to him."
I practice threading those dashed white lane markers indefinitely at 60 mph, as if they were long cones. That's about a 5' sideways shift ~ every 10'. At 65, they get tougher and the ride gets violent, but still can be done. At 120 every 3 can be threaded, and certainly a single shift is very easy at that speed. That's within 30 ft. A normal cage can't cover a lane width at 60 in that distance. The tires and suspension won't handle it. The cage will flip, or come close to flipping.
What's tough is having a deer drop out of the sky ~10ft in front while doing 70, snapping to go around where he's not going to be in a few msecs, and having the thing put on the brakes at 3' closing, and turning to watch you hit him in the ass. The last snap back up to brace for the hit to avoid getting the bike slapped right down is critical. LOL.
